Installing the Fan Assembly
To install a fan assembly, follow these steps:
Step 1
Hold the fan assembly with the fans facing to the right.
Step 2
Place the fan assembly into the front chassis cavity so it rests on the chassis, and
then lift the fan assembly up slightly and align the top and bottom guides.
Step 3
Push the fan assembly into the chassis until the captive installation screws meet
the chassis.
Step 4
Tighten each of the two captive installation screws.
Step 5
Verify fan assembly operation by checking the fan assembly LED. (See
Figure 3-5.) The Fan LED turns green when operating properly.
